    1  == P3.11       Ghost positions on the SCICAM ==
     1== P3.11        Check the acquisition procedure ==
    22•       **Phase**               :       3 
    33•       **Status**              :       Draft   
    44•       **Category**            :       Nighttime testing (functionality and operability) (C4)
    55•       **Recurrence**  :       once at commissioning
    6 •       **Duration**            :       50 minutes
     6•       **Duration**            :       2 hours
    77**Description**
    8 •       Locate the ghost positions at the SCICAM for on-axis and off-axis sources.
     8•       Verify the acquisition sequence for SHARK-NIR
    99**Prerequisites**
    10 •       Atmospheric conditions: photometric.
     10•       Atmospheric conditions: should be able to see bight stars on sky (preferably close to zenith?).
    1111•       Authorize SHARK-NIR on the SX side.
    12 •       Bright stars as targets.
    13 •       AO working.
     12•       Suitable bright enough target (including the possibility of performing AO).
    1413**Procedure**
    15 •       Center the bright star (on-axis) and for varying observing conditions, obtain short and long-exposure images to locate the ghosts/features at the SCICAM.
    16 •       Repeat this for every science filter.
    17 •       Repeat the above two which has one (or more) bright stars off-axis as well.
    18 •       Separate the ghosts from the filter defects if any (previously located/known).
     14•       Start the acquisition sequence: collimating the telescope to reduce the aberrations, close the loop and produce better ASM flat, NCPA estimation using phase-diversity algorithm, close SHARK-NIR tip-tilt+NCPA loop, and check the PSF quality at SCICAM.
     15•       Save telemetry (open and closed loop of the ALPAO DM).
    1916**Success criteria**
    20 •       xxx
     17•       Successful acquisition sequence.
    2118**Notes**
    2219**LBTO support**
    23 •       Support from LBTI/LBTO?
     20•       SOUL-AO support
